Thomas Szepe (hg1) added a comment to D2734: Buffer Protocol for bgl.Buffer.

Actually I don't have tested it, I also don't have experience with the buffer protocol and if there are no other issues with it.
Did you have tested the buffer also with some of the other bgl function calls like glTexImage2D()?
Does slicing the buffer still work?

Marcus Richter (mstuff) added a comment to T51965: Custom Bone Shape Wireframe setting affects wireframe thickness.

It seems to be the last added bone that creates the issue, not necessarily the last bone in the hierarchy.

Bastien Montagne (mont29) triaged T51965: Custom Bone Shape Wireframe setting affects wireframe thickness as "Confirmed" priority.

It’s the thick outline of first bone that is abnormal here… Adding a third bone will also bring it back to usual width.

Paolo Acampora (pkrime) added a comment to T51964: Can't sort Linked objects transparency in viewport.

while this report is indeed about a transparency issue, this one is different as it is not about having a better sorting in blender (not going to happen anytime soon), but about the "transparent" flag being ignored when dupligroups are visualized.

Ivan Cappiello (icappiello) added a comment to T51964: Can't sort Linked objects transparency in viewport.

@Bastien Montagne (mont29) since 2.79 is going to be last stable build till the official 2.8 release, i thought it could be worth a look at this patch since, even if doomed, BI will stay as long as needed to make 2.8 stable. What benefit could come from not having a workaround for that issue in 2.79 as long as it doesn't break anything else?

Bastien Montagne (mont29) added a comment to T51964: Can't sort Linked objects transparency in viewport.

I think this should be tested against Eevee engine in Blender2.8 then, really not worth spending time on this for BI currently, since it's doomed to be removed.

Ivan Cappiello (icappiello) added a comment to T51964: Can't sort Linked objects transparency in viewport.

@Paolo Acampora (pkrime), i remember you wrote for us a patch to fix that while we were rendering our animated feature GL previews. I think it's here https://developer.blender.org/T48983. @Bastien Montagne (mont29) We are stil using it in studio, even if rejected (and still unclear to me why) i think it could be at least a good starting point to address the issue, can you please consider it?

I'm a little confused now - these 3D previews come from the different blender versions (yours and official 2.78)
but obviously the bottom one, which is the experimental one, is different. The Render result is the same in both cases tho:

I doesn't contain any other stuff so it should be safe. Now that the fix is committed, tomorrow's build from builder.blender.org and 2.79 will have the fix as well.

Marin Myftiu (mm25) added a comment to T50856: Blender is not responding after minimizing [AMD].

I think I got this...had this hapening each time I turned off the discrete (AMD) GPU of a laptop to use only the apu: switch back to dual graphics and no problems.
Looks like triple buffering in User Preferencs > System > Window Draw Method is to blame and it should also be the one selected in ' Automatic'. All other options do not cause the freezing. Another thing I noticed is that it makes no difference if you enable triple buffering in your gpu driver options, it just doesnt like it on some models :P
Hope that helps...

Just to add a bit of extra info in case it is useful, blender 2.8 crashes for every engine on my machine, not just Eevee. I have tried BI, Clay and Cycles. Pressing TAB on the default scene using any of these engines crashes Blender immediately.

I don't know why this is not getting enough attention. We should make Blender use Overlap as 'Automatic' when it detects an affected card, not specify it manually.
